Windows Defender Exploit Guard ASR VBScript/JS Rule

in ,

Microsoft has been adding to Windows 10 the features of the Enhanced Mitigation Experience Toolkit (EMET) in to the OS. On the 1709 release they added more features and expanded on them as part of Windows Defender Exploit Guard One of the features of great interest for me is Attack Surface Reduction. I have used this feature in EMET with great success as a mitigation to many techniques that abuse built in functionality in Windows. One of the rules of great interest to me is the "Block JavaScript or VBScript from launching downloaded executable content" rule. With the greater visibility now in Windows PowerShell many of us as going back to the old and tested Windows Scripting Host languages and old techniques that have worked for so long.

Basics of The Metasploit Framework API - IRB Setup

in ,

Those of you who have taken my "Automating Metasploit Framework" class all this material should not be new. I have decided to start making a large portion of the class available here in the blog as a series. 

On this post I will cover the basics of setting up IRB so we can start exploring in a general sense the Metasploit Framework API. The API is extensive and sadly it would take quite a bit of time over it all, in the series I will covers the basic API calls and provide enough knowledge so you can continue learning the rest on your own or as needed. 

For this you need to be running a development environment. The Metasploit team has documentation on how to setup one https://github.com/rapid7/metasploit-framework/wiki/Setting-Up-a-Metasploit-Development-Environment 

If you are new to Ruby or come from another language and are learning the syntax here is a Ruby Primer.

Sysinternals Sysmon 6.10 Tracking of Permanent WMI Events

in , , ,

In my previous blog post I covered how Microsoft has enhanced WMI logging in the latest versions of their client and server operating systems. WMI Permanent event logging was also added in version 6.10 specific events for logging permanent event actions. The new events are:

  • Event ID 19: WmiEvent (WmiEventFilter activity detected). When a WMI event filter is registered, which is a method used by malware to execute, this event logs the WMI namespace, filter name and filter expression.
  • Event ID 20: WmiEvent (WmiEventConsumer activity detected). This event logs the registration of WMI consumers, recording the consumer name, log, and destination.
  • Event ID 21: WmiEvent (WmiEventConsumerToFilter activity detected). When a consumer binds to a filter, this event logs the consumer name and filter path

In version 6.10 it tracks the creation and deletion of __EventFilter Class, Any Consumer Type Class and __FilterToConsumerBinding Class.
